Search verified manufacturers from inside Claude or ChatGPT.

SupplySpark exposes its supplier database as an MCP server and a REST API. Ask your assistant for "GOTS-certified hoodie manufacturers in Turkey under 300 MOQ" and it searches SupplySpark directly — MOQs, lead times, certifications, evidence, and a profile link for every result. The assistant gets a preview of the top 5 per search with total counts, and every result links to the complete profile on supplyspark.co, contacts included, no account needed. The full ranked list beyond the first page, exports and the Spark agent are on Pro.
